Mullen's Dairy Bar has been honoring the "Mullen's Winter Tradition" since 1932. The tradition says that when the temperature is -20° or colder single dip ice cream cones are free. The temperature dropped well below -20° Saturday and the dairy bar was packed.

According to Adam Keepman, Managing Partner/Chef at Mullen’s Dairy Bar, “We are excited about today. This is the first time we’ve seen this temperature since my brothers and I took over operations in 2016, so I’m not sure when the last time Watertown saw ‐20 degrees.” Keepman joked, “Rumor has it that the Mullen’s brothers would make customers eat their free ice cream cones outside. We don’t plan on continuing that part of the tradition.”

Mullen's Dairy bar is located at 212 W. Main Street in Watertown and is open until 9 p.m. Saturday.

If you can't get there Saturday then you likely have multiple chances to score the free ice cream this week with a blast of dangerous cold.
